AuxiLlAv FIRE-ALARM SYSTEM. 'aeiterreanou -forming part'of. Letter-armut No. 761,636, dated may 31,1904.

A l mutation mammary 30,1964. semi no. 189,922. (Nomad.)

to'n, it may concer-m. it knownl that I, WILLIAM LIVINGSTON DENIo, a resident of Rochester,in the'county of. Mon`roeand.- State of -New York, have in- 5 vented certain new and useful Improvements 'gin Auxiliary Fire-Alarm Systems; and I do 'hereby declare the following'to be 'a full, clear,

and exact description of the invention, such as'wlll enable others skilled in the-art to which push 13. The inner end of part 13 when 50 moved inward moves against spring 15, tilt- -ing the arm 16, pivoted at 17, and carrying beyoud the pivotarmaturelS of magnet 19, connected inthe auxiliary Wire 3. The armature when moved by the push 13 or by the mag- 55 net releases the escapement of, the motor,

allowing it to turn the signal-wheel 22, breaking and making the main current. MovementV I0 it pertains to make and u'se the same.' of the armature also allows pivoted lever 23 1'?, lThis invention relates to re-alarm appat is lever operates in thesameway when the armature is moved by the magnet 19. When the motor-is wound by moving arm24 to the 4position `of Fig. 1, the end 25, insulated from.4 Ing or district, whereby the box can be operth l transmitter for a selected building or district ln the accompanying drawings, Figure 1 is h xa'r'rontview of the auxiliary box with. the

angles toV Fig. 1, 4the cover and box being broken away onthe central vertical transverse '2 plane. 'Fig'. 3 is a view of the `escapemen't 2 and connecting springs 3031, as seen in :and certain releasing `parts detached. Fig. 4' Fig.- 6. v

and armature, constitutes -an auxiliary box, 75 started at the box itself by push 13 or from a distance by operation of either of the man-- u-al and automatic controllers 4 or by an orindicates a central oiiice where is a source of d' or to'send an alarm before the thermostats operate. The dotted position of the switch is `t e normal one.. After the movement has to distant fire-alarm boxes'2. Numeral 3 indicates a third wire, called the auxiliary wire, which is connected to one side-of circuit 1 and whichis substituted forl said -side when either.- of'the'; manual or automatic thermostatic circuit-controllersf4 is operated.

e auxiliary fire-alarm box4 is shown on 40 Sheets 1 and 2. The operating mechanism is mounted on an insulating-plate `6 on a frameor body having a cover. 8, which when on, pushes (by pinlO) pin 9 and its slide 1l to the left, engaging and holding the 'flange at the l5 top of the glass cover 12, whicb'cover is over v'the push 13, which is normally down, but

which'can bepu'shed up'w-henthe glass cover. vis removed or broken until'it is locked'by spring-arm 14 falling intogroove 12? in said lar signal begins to be sent. At the-same cut out.

vThe resistance device which spans the local A signallamp 27 at the auxiliary box consists of an insulating body 32, having a resistance-conductor 33 extending-back Aand forth thereon. It will beseen'that in removing the cover 95 8, F ig. 5, the tension of'spring 14 vis released' to guard against accident of 'starting thebox.

.In Fig. 6jan` ordinary manual switch 34 is The Signal-bex, with the releasing magnet started the circuit is opened 'by a special notch "l I tlme the resistance of the tripping-magnet is` a@ I y reien shown, the switch-arm being normally in dotted position holding wire 1' closed, but when operated .changing the circuit to auxiliary wire 3. This is also the operation if a manual or automatic switch is used. Lever 23 may be thrown forward by spring 23 on its pivot.

The manual and'automatic'circuit-controller abovereferred to is describedand claimed in my application of even date herewith, Serial No.4 189,924.

Having described my invention, what 1 claim as new, and desire to secure by Letters Patent, is- V 1. The combination of an auxiliary fireaiarm box, a central oice, a' normally closed circuit between said box and office, a battery vin the circuit at the oce, springs 26, 27, at

the box, means normally holding the springs together closing said circuit, a box-releasing magnet, an auxiliary wire extending from the box to the place to be protected, normally open circuit-.controllers between the auxiliary wire and the normally closed circuit, a magnet 19 in the auxilliary wire, the latter being normally open at the circuit-controllers, means operated by said magnet for releasing the box and means at the box for separating the springs 26, 27, in the normal circuit, and closing a signal-circuit including the auxiliarywire and a part of the normally closed circuit, said signal-circuit cutting out said magnet.

2. The combination of an auxiliary firealarm box, a central oice, a normally closed circuit between said box and oiiice, a battery in the circuit at the oiice, contact-springs 26,

27, 30, and 31 at thebox, two of said springs,

26, 27, being normally connected closing said circuit, a box-releasing magnet, an auxiliary wire extending from the box to the place to be protected, normally open circuit-controllers between the auxiliary wire and the normally closed circuit, a magnet 19 in the auxiliary wire, the latter being normally open at the circuit-controllers, means operated by said magnet for releasing the box, and means at the box for separating said contact-springs 26, 27 of opening the normal circuit, and for connecting contact-springs 26, 3Q, 31, closing an alarm-circuit.

3. The combination of an auxiliary firealarm box, a central oice, a normally closed circuit between said'box and oce, a battery in the circuit at the oliice, springs 26, 27 at the box, means normally 'holding the springs together closing said circuit, a box-releasing magnet, an auxiliary wire, normally open circuit-controllers between the auxiliary wire and the normally closed circuit, magnet 19 in Y the auxiliary wire, the latter being normally open at the circuit controllers, means operated by said magnet for releasing the box and separating springs 26,|-27 inthe normal circuit and closing the signal-circuit, 'a circuit-breaking wheel and spring for the signal-circuit, a wheel havinga preliminary signal notch in advance of the number-sending notches'. s 4
